Multiple Emulators on one CD-R?

I'm awaiting my first ever Sega Dreamcast from Amazon.com... I wish I had bought one when it was first released since all this neat stuff can be done with it. It's used but as long as it works I will be happy! (Plus it only cost me $30)

Anyway, while waiting for the dreamcast, I've been researching everything about emulation. One question that I have is: IS IT POSSIBLE TO HAVE MORE THAN ONE EMULATOR (SNES, NES, SEGA, etc) ON ONE DISK? Since all of my NES roms don't add up to much I wanted to add other emus and roms to the disk instead of making two disks...

Just something to think about. Thanks!

you can sexy it up and customize your own menus.

now using it to make multi menu discs can be a huge pain in the ass. when you have problems use this...

IF YOU GET PISSED AT TRYING TO FIGURE THAT OUT
I can very easily help you burn roms to your disk. DC homebrew and emulators are usually supplied in three forms. SBI's, disc images (*.cdi and *.nrg) and what you'll want to be using to add roms to a disc is what we call Plain Files. Plain files are everythin you need, just not in a disc image format.

The tool of my choice when burning plain files is fakue's bootdreams

When you have plain files you can click and drag your roms or your own backgrounds or whatever to the folder. When your done with that you start up bootdreams and select where that folder is. from there you can either make and image and burn it or write an image to your hardrive to be burned later.
easy as pie.

you can also use Dc Hakker, dc hakker is a boot disc, you just burn it once, then you but all your emu/homebrew/apps on another disc, with the roms too, i think. its a handy way if you don't want to get into making sbi's, but its less neater than dream inducer (sbi).
